To all whom it may concern.'

Bc it known that ll, BENJAMIN C. BARTLE- BAUGH, v siding at Wheeling, in the county of Ohio and State of West Virginia, have invented certain new and useful Improvements in Gas-Stoves; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art` to which it appertains to make and use the'same.

This invention relates to improvements in gas heating stoves or furnaces.

The object of the invention is to provide a stove of this class so constructed that perfect combustion will be insured, thereby producing a'maximum amount of heat with a minimum consumption of gas and which also consumes all the moisture and poison in the gas, thus avoiding all danger of monoxid gas poisoning.

, Another object is to construct a stove of this character so that the air and gas which passes outthrough the burner will be thoroughly heated and dried.

Another object is to provide a. gas stove Witha channel at the back for carrying od the odors'and having means for -creating draft or suction through said channel and rpeans for directing the odors back intothe Another object is to provide a burner having outlets for the fuel, so arranged that a maximum amount of air is fed to the body of the fire, thereby producing a thick flame which retains all the poison in the gas and consumes it without permitting any to pass off to the atmosphere.

With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully ydescribed and claimed.

In the. accompanying drawings: Figure 1 represents a transverse vertical section taken on the line lof Fig. 2; Fig. 2 is a longitudinal vertical section taken on the line 2-2 of Fig. 1'; `F ig. 3 is a horizontal section taken on the line 3-3 of' Fig. 1; ifi 4 is a similar view taken on the line 4--4 o Fig. l; Fig. 5 is a detail vertical section taken on the line 5-5 of Fig. l.v

ln the embodiment illustrated, a shell or casing l of any desired size and form is shown which is made air-tight throughout except at its bottom and front where opena citizen of the United States, rcy ings are provided for the intake of air to aid in combustion.

An upright partition 2 is spaced from the rear wall Sof the casing 1 and terminates near the top and bottom thereof to form a channel L for the passage therethrough of the current of heated air and the obnoxious odors from the gas which are carried under and around the burner to be described for the purpose of heating and drying the fuel in the burner in order that a mixture of hot dry gas and air may be fed through the burner openings for ignition. This partition 2 has a V-shaped recess in its upper edge, which is designed for creating suction or draft in the channel at .the rear of said partition, an entraining action being brought about by the air entering below the plate 9 and mingling with the products Vof combustion and passing over the upper edge of the partition 2.

The front wall 5 of the casing has an air inlet opening '6 extending transversel thereacross intermediately of its ends, pre erably at a point about midway the height thereof and the lower wall of said opening is rolled outwardly to form a reinforcing lip 7. A transversely curved shield 8 is secured at one edge to the front wall 5 of the casing von its inner face below the lower wall of Patented lllec. 2, i915..

the opening 6 therein with its concave face disposed inwardly and extending adjacent the burner to be described for directing the products of combustion and odors back into the flame.

A plate 9 is secured at its sides to the end walls of the casing with its lower edge arranged immediately between the upper and lower end of the opening 6 in said front wall. The upper wall of said* opening is deflected outwardly and is provided with a hood 1l whereby a mouth is formed between it and the lower edge or end of the plate 9. rlhis plate or partition 9 is inclined upwardly y:and inwardly with its upper end engaging the top 0f the casing l in advance of the obnoxious gases for directing them over the partition, and as a partition to separate these gases lwhich are retained in the coinbustion chamber from the chamber 10 formedbetween said plate 9 and lthe walls bottom to support auxiliary of the casing in advance thereof. Als shown, the plate 9 is provided at its opposite side edges with right angularly disposed anges 9 which are attached to the end Walls of the casing by suitable fastening elements (see Fig. 1),l lThe odors and other materials in the heated air being deflected by said plate 9, over into the channel d at the rear of the stove and are conducted back to the Haine where they are consumed.

A burner 12 is mounted in the'lower half of the casing 1 with the gas discharge openings 13 thereof disposed opposite the lower Wall of the front opening 6. This burner 12 is in the form of a cylinder of a length corresponding to the width of the casing l and of a diameter less than the depth or thickness of said casing. This cylinder 12 is closed at both ends and is designed to be supported in the casing between the curved shield 8 and the partition 2 at the rear of the casing by any suitable means with the gas discharge openings 13therein arrangedL substantially Hush with the lower end of the opening 6, in order that air admitted through said opening may be mixed with the gas passing out ofthe burner openings to provide a more perfect combustion.

By constructing the stove casing with the comparatively small opening in the front wall thereof, and arranging the delecting plate 9 and burner in the manner shown and described, suihcient fresh air is admitted through the opening 6 and the open combustion, and the dedecting plate directs the products of combustion rearwardly over the partition 2 so that there is no danger of the obnoxious gases passing out into the -surroui'iding atmosphere, said gases being-directed back to the 'burner andnconsumed. Moreover, by the positioning of the.`plate 9 with its lower end disposed near the center of the casing front walland its upper end engaging the top near the rear thereof and adjacent the `partition 2, an enlarged combustion chamber is formed above the burner tapering toward its discharge end so that the products oit combustion are retained therein a sufficient time to substantially exhaustitheir heating capacity before they passthrough, the restricted discharge at the tapered end of said chamber, thereby greatly increasing the heating' power ofthe stove.` This arrangement of the plate 9 also provides an heating chamber 10, the heat radiating from said plate serving to heat the air in the' chamber 10 which heats the'walls of the chamber 10 said walls radiating the heat therefrom to, the surrounding atthe triangular casing messia are spaced laterally to permit the free passage of air between the respective series. As shown, three series of inlet openings 13 are provided and each comprises a multiplicity of fine perforations and the spaces between these series permits the air admitted through the opening 6 to combine with the gas while burning, the air being supplied on each side of each series of openings and thereby feeding six times the amount of air to'. the body of fire, as is fed by one row of outlets or openings which' produces a flame of maximum heating capacity with a minimum consumption of gas.

The cylinder l2 is provided in its side opposite the discharge openings, with a plurality of longitudinally extending spaced coneshaped inlets 14 for receiving gas at dilierent points and passing it into the cylinder, whereby a better and a lquicker mixing of the gas and air in the burner is provided and which also provides for the entrance into said cylinder of a great volume of air to aid in -ccombustion This cylinder 12 has a longitudinally extending horizontally disposed partition 12 secured therein below the discharge openings 13 thereof, with its ends spaced from the ends of the cylinder to provide for the passage around said ends of the mixed air and gas, which is designed to pass out through the openings 13, said air and gas having first been-heated and dried in the cylinder below the partition l2 A'gas distributing chamber or casing 15 is disposed in the lowerportion of the stove below the cylinder 12 and may be of any suitable or desired shape, being here shown substantially triangular in forni with, a gas inletpopening 16 in the larger end wall thereof, having a supply pipe 17 secured therein and extending outwardly through the front wall of the casing and provided with a nipple 18 for connection with a hose or other supply pipe (not shown).

VA plurality of gas discharge pipes 19 extend laterally from the apex and sides of or chamber 15 and are out of aiinement with the inlet opening' 16 thereof, in order that the force of the gas enteringthrough the supply pipe may be broken up in the chamber before discharging it through the pipes disposed in a plane y19., Each yof these pipes 19 'is provided with `20 extending upwardly at ri ht angles to the body of the pipe and provi ed with a small discharge aperture 21, and which are positioned to open into the cones 1d of the cylinder 12 and thus provide for the entrance of a strong stream of gas into a nipple vthe burner which commingles with the air f red in the cones 14 and forms a perfect mixture for ignition.

By constructing a gas stove or furnace in the manner above described combining therewith the particular distributing chainmeaaia ber specified, the gas leaving the cylinder 12 is burned in a flame which retains and consumes all the obnoxious poisons in the gas and prevents them from passing od into the atmosphere, thereby rendering the stove perfectly safe for use, there being no possibility of monoxid gas poisoning.

The flame referred to is a thickened flame produced by the great quantity of air which is mixed with the gas as it passes into the burner and the air mixed with the gas passing out of the burner owing to the peculiar arrangement of as with spaces between them so that/,air is ed between the flames or rows of ire on top of the burner. By the peculiar construction of the burner described herein three times as much air is fed into the burner with the gas as is fed by the ordinary burner and three times the amount of air is fed to the flame while burning. This vfeeding of air with the gas and to theflame produces a thick body of fire on top of the burner that looks like quivering hot lead and not a thin sheet bf Haine as is produced by other burners.
